Clicking gravatar opens a blog that isn't mine

When I post a comment on someone else's blog and then click my image link, I get taken to a blog that I set up and then transferred to another WordPress user.
This is no longer my blog, I do not want to be associated with it, but it's still popping up when I click on my own image. Have checked everywhere in Gravatar settings, but cannot figure out how to unlink it.
I tried putting my own blogs in under websites in my Gravatar profile, but it is not taking me to either of these, just to the other blog... that, as I said, I don't want to be associated with.
Help!
